How to use Nios to save the output of a module into a file in pc?

Hi all, I'm using the cyclone2 ep2c35 fpga and I would like to save the system output in pc for further analysis. I've heard that using Nios is a somewhat efficient and easy-to-use way to achi...

Thanks for your reply.

The module is a sigma-delta modulator of 3-order-and-5-level, thus its output is a sequence of numbers with width 3 varying from -2 to 2. The sequence looks like, for example, -2, 0, 1, 1, 2, 0, -1 ...

The modulator is working at the frequency of 20MHz. But since its input rate is 5MHz, its output rate is 5MHz too.

Right now I really have no idea of how to make this happen. I have some immature thoughts of using JTAG UART to realize it. But I don't know whether it is workable.

Thanks again.
